# XS4ALL: Custom training strengthens security awareness and development consistency XS4ALL has long been recognised for its commitment to security, privacy and reliability. To further strengthen the quality of its software development practices, the internet service provider partnered with Dawn Technology to deliver a tailored training programme focused on secure coding and consistent development methodologies. - PHP **Discovery**## From awareness to improvement XS4ALL was confident in the security of its codebase, but wanted to identify opportunities for improvement and create greater consistency across its development teams. The challenge was not simply about increasing technical knowledge; it was about building a shared awareness of security and privacy throughout the organisation. The development team consisted of experienced and highly critical professionals who would only be engaged by training that offered genuine technical depth and practical value. One of the senior developers had previously worked with Dawn Technology and recommended us as a training partner. From the very first meeting, it became clear that there was a strong match: technically skilled, pragmatic and capable of engaging with the team at a high professional level. **Design & development**## Training built around real code We developed a fully customised training programme that began with an extensive preparation phase. Through collaborative workshops and in-depth individual interviews, we gained a detailed understanding of the team's challenges, objectives and development priorities. The training itself was tailored specifically to the XS4ALL development team. Participants worked in small groups using XS4ALL’s own codebase, creating immediate relevance and engagement. This approach ensured that every lesson could be directly connected to real-world situations and challenges faced by the team. Our trainers introduced new perspectives, highlighted concrete improvement opportunities and combined technical depth with practical application. The objective extended beyond knowledge transfer; it was about establishing a shared mindset and a consistent way of working across the entire development organisation. **Conclusion**## Greater consistency, stronger awareness, better foundations The custom training programme proved to be a valuable investment. The development team now operates with a stronger shared awareness of security and privacy, supported by a more consistent approach to software development. The practical techniques and insights gained during the training are applied on a daily basis. The team has a clear understanding of where improvements can be made and how those improvements can be implemented effectively. For Ronald Renes, Dawn Technology has become the first point of contact whenever significant changes or new technical challenges arise. The trust built during the project extends beyond management and is shared by the entire team that participated in the programme.
